Gardeners' Notes:

Neutral coriaceous On Dec 9, 2014, coriaceous from ROSLINDALE, MA wrote:

This is advertised as the first reblooming lacecap hydrangea. Because it blooms on both old and new wood, bud blast or dieback from exceptionally cold winters should not wipe out bloom the following summer. (Bloom time is from early summer till fall.)

Flower color depends on soil pH, pink on alkaline (high pH) soil to blue-purple or blue on acid (low pH). The big showy sterile outer florets are semi-double to fully double.

According to the originator, at maturity this shrub is 2-3' tall and wide.

This plant is hardier than indicated above, to Z5a.

The cultivar name is 'MAK20'. "Tuff Stuff" is a proprietary trade name.
